    Count all nested stack resources with DB operations

    The count is performed in 2 parts
    - A function which builds a list of all nested stacks
      by recursively calling stack_get_all_by_owner_id
    - A query which counts resources which belong to the list
      of stacks

    Considering this will be the basis for fixing bug #1455589 then this
    approach is appropriate for backporting to stable/kilo, but master would
    ideally replace this soon with a new Stack attribute that stores the
    calculated resource count.

    Partial-Bug: #1455589
